Jim:

Let me know how you make out with this. I replaced a 16' sections of
basement wall a few years ago w/ block and surface bonding cement. I
want to do more a slightly different way. My basement is beachsand w/
huge rocks in it. The beach sand concrete is crumbling in areas and I
want to form a concrete wall against the solid rocks. Either that or
have gunite or shotecrete sprayed on it but no contractors ever get
back to me.

Good luck with your project!
